I'm not really sure the queue is serving its intended purpose. It seems to be largely filled with game ideas, but how many actually come to fruition? I know I've posted a few times in there, but then had to withdraw because I haven't got time to host. So it's not really a very accurate queue, and sometimes the conventions of a queue (i.e. the first in the queue being the next up) aren't very stringently followed.
The other problem is the lack of small games, but this may be due to the fact that the queue is encouraging people to post their grand ideas that aren't going to come to fruition, rather than posting what they are actually going to be able to do. If the queue were for games that were ready to go, then I think it would serve a more useful purpose, and would encourage small games.
